To (ir/ ZZ whom it may concern:

,type-inwhich, motion imparted to a masterwheel by sweeps attached to the periphery thereof is, transmitted through suitably-ar-.

ranged gearing to a shaft rotatably mounted in the supporting-frame of the horse-power.

The principal object of the invention is to provide in a horse-power of thetype specified an improvedarrangement of power-transmitting gearing bymeans of which the strains imposed upon the ymaster-wheel in operation are .so distributed as to produce a balanced effecttupon the master-wheel and to relieve the various parts. ofthe supporting-frame of vthe horse-power, of any localized excessive, strain tending to distort the frame and interfere with theoperationof themechanism.

A further object of theinvention is to pro-l Avide an,y improved horse-power of the type. specified inwhich the elements are so arranged that a minimumlof wear willresult from the use of the ,'mechanisma'nd the durability of the structurewill be accordingly increased.l lnattaining the objects above mentioned IL 1 prefer4 tomake .use of the novel construction and combination of parts'of a horse-power, as hereinaftend escrib'ed, illustrated inpreferred form in the accompanying drawings, and-having the novel features thereof particularlyset i forth in .the appended claims.

` Inthe drawings, Figure 1 is a plan view-of' the improved horse-power. in transverse section.

Referring to the d'rawings,'in which corresponding parts are designated by similar characters of reference throughout, F .designates the supporting-frame f of` the. ho rse-power, which is kmounted on wheels W for convenience in transportation and is provided with a tongue T,bymeans of which the horse-power may be drawn from place to place by draftanimals. The frame F is of substantially Fig. 2 is a view rectangular form, comprising longitudinal members 1 1 and transverse members 2 2, secured together in any suitable manner. The frame F afords support. for aI master-wheel 3, arranged for rotation in ahorizontal planev and supported in any preferred manner. The master-wheel 3 is preferably double-cogged,

as shown,so that` it may be' reversed from time to time to equalize the wear, and so. prolong the life of the apparatus. 'In the construction illustrated the master-wheel r3 .is supported upon slightly-tapered beveled pinions 4, mounted upon brackets 5, which4 are rigidlyl secured upon the frame-F, and the 'master-Wheel is heldagainst lateral ,shifting` by guide-rollers 6, arranged to turn on vertical axes, as shown, and mountedupon brack- Motion-is imparted to the master-wheelby y sweeps, (not shown,) which may be attached to the periphery of the master-wheel in any preferred manner and provided in any desired kor convenient number.. rlhe power applied to the master-wheel is transmitted to slightlye are mounted in bearings fastened upon the frame F, and the motion imparted thereto by the pinions 7 and 8 is transmitted to a main drivingshaft 11, arrangeditransversely of the frame, as shown. The means employed for tapered pinions 7 and 8, supported-upon shafts i i 9 and 10, respectively. The shafts 9 and 10 transmitting the motion ofthe shafts 9 and 10 tothe main shaft' 11 will now be described.

Rigidly mounted upon the main shaft 11 intermediate of its ends and arranged to turn in the longitudinal median plane of the frame F is a large double-beveled gear 12. With the teeth upon one faceof the double-beveled gear 12 beveled pinions 13, mounted Aupon the `shafts 9, are adapted to mesh, and the strain imposed upon the gear 12 by the pinions-13 the gear 12 at points directly opposite the points of engagement of the pinions 13. The

ybeveled pinions 14 are rigidly attached to shafts 15, supported in bearings upon the frame F, as shown. These shafts 15 also bear beveled pinions 16, which mesh with similar pinions 17, which are fast to the shafts 10, above mentioned.

By means of the mechanism described in the foregoing paragraph the movement transmitted to the tapered pinions 7 by the masterwheel is transmitted directly to the double-beveled gear 12 by means of the beveled pinions 13, mounted upon the shafts 9, upon which the pinions 7 are secured; but the motion imparted to the pinions 8 is transmitted indirectly to the gear 12 through the intermediary beveled pinions 16 and 17. Consequently the rotation of the pinions 7 and 8, which is in the same direction, is applied to opposite sides of the double-beveled gear 12 in opposite directions, so that the strains imposed upon the double-beveled gear are balanced by being applied at opposite points; but the full effect of the power applied to the pinions 7 and 8 is realized in driving the gear 12. Furthermore, by placing the pinions' 7 and 8 in the positions shown the strain upon one half of the master-wheel is balanced by an equal strain upon the other half, and there is no tendency to produce a lateral bodily movement of the entire master-wheel. In consequence of the equal distribution of the strains upon the master-wheel and the double-beveled gear 12 the strains upon the frame are also equalized and distributed in such manner that the frame is adapted to withstand them effectively without becoming distorted thereby. In the operation of the horse-power the movement of the master-wheel is transmitted, through the gearing above described, to the main driving-shaft 11, and a steady uniform movement of the driving-shaft is obtained. This movement is transmitted from the driving-shaft to the machinery to be operated by means of any preferred form of power-transmitting devices. As any form of transmission mechanism adapted to the particular circumstances of any case may be employed to transmit movement from the shaft 11 to the machinery to be operated by the horse-power, the description and illustration of such transmitting devices are regarded as superiiuous.

In the description of my invention I have limited 'myself to the principal features thereof and have omitted all detailed description of mere mechanical details of construction, which may be varied at will without departing from the spirit of the invention. In the construction of the frame F especially the arrangement of the interiorelements may be varied to suit the whim of the constructor without departing from the spirit of the invention, and I have merely shown a convenient arrangement of brackets and braces to hold the shafts and gears in operative relation.

In order to bring the horse-power to rest quickly and to prevent the sweeps from striking the draftanimals when it is desired to stop the horse-power, it is desirable to provide a brake of any ordinary type to operate directly upon the master-wheel at the inner margin thereof. In the form of the invention illustrated the brake comprises a block 20, arranged to slide in guides 21, supported in the frame F and preferably disposed in the plane of the gear 12. The block is operated by means of a pivoted brake-lever 22, projecting upward from the frame and preferably arranged to engage a segmental rack 23 to hold it in any desired position.

I-Iaving thus described the construction and operation of my invention,wl1atl claim as new, and desire to secure by Letters Patent, is

1. In a horse-power, a master-wheel, a main driving-shaft, a double faced gear rigidly mounted upon said shaft, pinions meshing with both faces of said double-faced gear at dialnetrically opposite points, and suitable driving connections between said master-wheel and Said pinions.

2. In ahorse-power, a master-wheel, a main driving-shaft diametrically arranged within said master-wheel, a double-faced gear rigidly mounted upon said shaft, pinions meshing with both faces of said gear at dian'letrically opposite points, direct driving connections between the master-wheel and the pinions engaging one face of said double-faced gear, and indirect driving connections between the masterwheel and the pinions engaging the other face of said double-faced gear.

3. In a horse-power, a master-wheel disposed in a substantially horizontal plane, a main driving-shaft also disposed in a horizontal plane, a double-faced gear mounted on said driving-shaft, pinions engaging one face of said gear at diametrically opposite points, direct driving connections between said pinions and said master-wheel, pinions engaging the other face of said double-faced gear at points directly opposite the points of engagement of the first-mentioned pinions, and indirect d riving connections between said last-mentioned pinions and the master-wheel.

In testimony thatI claim the foregoing as my own I have hereto affixed my signature in the presence of two witnesses.

DAVID JOHNSON.
